In the last few years, DevSecOps has been widely adopted among organizations looking to get proactive with their security. Traditionally, development teams would continuously implement and deploy new applications into the enterprise and security was an additional bolt-on at the end.
However, as the threat posed by cybercrime has increased, organizations have been ‘shifting left’ with their security and weaving it into the beginning of the development life cycle.
This offers significantly increased security benefits and means software vulnerabilities can be identified and remediated before they are exposed to the enterprise. The one drawback is around the additional time this takes. As a result, many organizations are also looking to automate their DevSecOps processes.
Automation is a critical feature of DevSecOps as it improves efficiency, cuts costs and can streamline operations. However, to get the most out of DevSecOps automation so it delivers real value to the organization, there are several challenges that must be considered first. But what are these challenges and how can they be overcome?
How to Approach DevOps Security Automation
When you first move to security automation, you’ll find some security tasks that can easily be automated and others that are harder to fit in. DevSecOps teams will need to use many tools to cover all their bases, but no one wants teams checking lots of different tool outputs. Making it easier to see what’s going on and where risk lies by consolidating security tools and results in a central platform is the way to go. This makes life easier by giving a single pane of glass. Everyone generally agrees that DevOps teams must adopt cybersecurity best practices, but testing takes time. Development teams don’t have time to learn, use and check lots of security tools on top of their existing workload. Automated solutions get to work without any real need for maintenance or management. These solutions trigger tools to work at the right time depending on the outcomes found without any manual input needed. This gives you and your team valuable time back to focus on other important matters.
Fitting DevSecOps Into Secure CI/CD Pipelines
The goal of CI/CD pipelines is fast delivery of build and release steps, typically through automation. A key goal of DevSecOps is to alert someone to a new problem as early in that automated process as possible. You need to develop solutions that don’t overwhelm CI/CD pipelines, yet allow flexibility for differing tech stacks, security tools and environments. What you need to ask is, have the latest changes caused any new and important security issues that should be reported before going live?
Doing DevSecOps Without Constant CI/CD Changes
Trying to manually run security tools on your entire application source code each day can be time-consuming and hinder your ability to keep up with daily changes. For security checks to keep pace with code delivery in a CI/CD environment, security automation is a must. Security products need to integrate into the development pipeline and enable both the development and security team to work together instead of just throwing things over the fence to each other.
Focusing on Issues Raised for Faster Remediation
All the artificial intelligence and machine learning (AI/ML) in the world isn’t going to remove non-issues better than a manual triage, so here we recommend being resigned to getting stuck. Treat the first run of a set of security tools as a normal security test. Expect hundreds of issues and be prepared to go through them and mark the false positives, duplicates and issues that just aren’t important right now. But do this with the expectation that you’re creating a baseline against which your future pipeline scans can be measured so you’re only alerted to new important issues. By automatically managing and recording the lists of real issues existing in every DevSecOps pipeline run, we can then concentrate on the differences. These new issues need to be flagged and then made easily visible and actionable for all teams.
Running Multiple Security Tools in CI/CD
DevSecOps includes setting up many automated security tools to cover the many types of security issues that need to be checked for. Many organizations run multiple security tools. However, as the number of security tools grows and the DevSecOps processes become more complex, many companies then realize the hardest challenge is to make sense of all of the test results within a short period of time. For some companies, this task of bringing together the results from all of these tools is a full-time job, and one ripe for automation.
Triaging Security Issues
False positives and nonsense issues are consistent problems for using security tools. Removing these gives better results and increases the chances that development teams will have a better relationship with DevSecOps processes. Organizations should build a list of issues that don’t need to be actioned and also use automated security tools to flag new issues and differentiate them from the previous backlog of issues. Automating the ‘best fixes’ across all issues also speeds up fix times, while reducing the workload on security teams.
Mapping Security to Development Processes
Dev and DevOps teams are under pressure to get pipelines running smoothly and don’t want security slowing things down or complicating it. By automating security testing in such a way that it can easily handle changes in repos and containers, organizations can overcome this challenge without compromising security.
Risk Prioritization
DevSecOps will increase the number of issues found as well as the speed with which they should be handled. In reality, only a small number of issues will pose a massive risk to the business. Being able to pinpoint the really big issues in real-time helps security know the big risks are being covered and allows developers to focus on the real issues, not lots of small bugs. You can also intelligently determine the changes in risk for quick and automated decisions in the CI/CD pipeline without slowing down the development team.
